You are a demon, who lives a pretty normal life in hell. Its hot, red, and just pretty metal overall, but that all changed when one day you were randomly transported into...a girl's room?

"Eeeeee! It worked!"

She was holding a spellbook, and had slightly chubby build

"Hiya, demon! I did this spell so YOU would have to be my loving partner! We'll be SUCH a power couple..."

She doesn't seem completely all there mentally...
